Our Employees

Our staff members come from varied backgrounds – from years of experience as a certified gemologist, to previous experience as owners of jewelry stores. After working together for over 30 years, we know jewelry.


Jan Marten’s mission is to provide clients a personal, educated and transparent experience in the jewelry business. Her knowledge and passion for jewelry stems from years of experience working with high-end custom designers, large carat diamond cutters, and respected industry professionals all over the world. Jan is a Graduate Gemologist and an Accredited Jewelry Professional certified by the Gemological Institute of America, the largest and most respected educational institution in the industry.

Jan grew up on the south side of Indianapolis and is from a family that always insisted upon honesty and giving back. Committed to creating a better world for all of us; Jan has volunteered her time and expertise to Assisted Living Facilities, Schools and Programs to help children in need. Continuing education is her passion no matter what edge, “we never should stop learning”.

Recently JEM made the decision to scale things back. JEM now has a smaller store where they are able to give each customer a more personalized experience. It was also important to JEM that the overhead remain low to pass the savings on to their clients. Jan will tell you she loves what she does and it shows! Creating jewelry for couples and individuals is her favorite thing to do – and the most rewarding. Her clients become part of her family and vice versa, Jan is attending weddings regularly being invited by her special clients! “I have “the gift of gab,” as my father always said, and consistently reminded me that “Much is expected from the person that to whom much has been given.”


William has been a jeweler for over 30 years, starting right out of high school. When asked what his favorite piece of jewelry is, he says “My favorite piece is always the next piece I’m working on.” His favorite part of the job is seeing the look on the client’s face when they open one of his hand-made creations. William is a true master of his craft and we are so grateful to be able to call him ours! William is insistent that no one ever leave JEM Jewellers with jewelry that has not been cleaned.


Mary Ann has a long history of working in a client based business. She learned early in her career how to listen to a client’s needs and wants, and works very hard to make it happen within a budget. Mary Ann has always had a love affair with diamonds and is a natural when it comes to finding that perfect engagment ring, birthday or anniversary gift. She prides herself in always putting the customer first and enjoys seeing happy smiles as they leave the store with their new treasures.​
